Some text showed up on my launcher telling me that I was using an outdated launcher and that I should update to this new one without Java. So I downloaded it, replaced my old Minecraft in the Applications folder with it, and removed the "Application Support" folder because I assumed it would just download a whole new set of interior-folders. So I go to run it and it opens up a loading bar titled: "Downloading Runtime." The bar gets all the way up to 59.90 - 59.92MB, gets stuck, reloads, gets stuck at the same place, and then I get an error popup saying "Unable to update the Minecraft Native Launcher." I first did this yesterday, gave up after a couple tries, then did it again today a full 24 hours later, hoping it was just a server glitch. My friends aren't encountering any problems with it and I was wondering what the problem is. It's incredibly annoying.
